SQL Server 2012 :: How To Extract One More Piece Of Data From The Column

I have a database table that was designed by someone else, and I'm trying to see if I can normalize the pattern. Here's the dummy table:

CREATE TABLE [dbo].[BadTox](
[PatientID] [int] NULL,
[Cycle] [tinyint] NULL,
[ALOPECIA] [tinyint] NULL,
[Causality1] [tinyint] NULL,

[Code] ....

All the column names in upper case are actually symptom names, and in those columns are values {NULL, 1, 2, 3, 4, 5} and they belong in a column, so the normalized structure should be like this:

CREATE TABLE Symptom (
PatientID INT NOT NULL,
Cycle TINYINT NOT NULL,
SymptomName VARCHAR(20) NOT NULL, -- from the source column *name*
Grade TINYINT NOT NULL -- from the value in the column with the name in uppercase
PRIMARY KEY (PatientID, Cycle, SymptomName));

I can untwist the repeating groups with the code I borrowed from Kenneth Fisher's article [ here ], but the part I'm having a harder time with is grabbing the information that's still left in the column name and integrating it into the solution...

I can retrieve all the column names that are in uppercase using this:

DECLARE @db_id int;
DECLARE @object_id int;
SET @db_id = DB_ID(N'SCRIDB');
SET @object_id = OBJECT_ID(N'SCRIDB.dbo.BadTox');
SELECT name AS column_name
, column_id AS col_order
FROM sys.all_columns
WHERE name = UPPER(name) COLLATE SQL_Latin1_General_CP1_CS_AS
AND object_id = @object_id;

but I can't figure out how to work it into this (that I built by mimicking Kenneth Fisher's article...):

ALTER PROC [dbo].[UnpivotMaxGradeUsingCrossApply]
AS
SELECT PatientID
, Toxicity
, MAX(Grade) AS MaxGrade

[code]....

The problem is that I need to extract the column names (where ToxicityName[n] would be). I can do that by querying the sys.all_columns view, but I can't figure out how to integrate the two pieces. About the only thing I have even dreamed up is to build the VALUES(...) statements dynamically from the values returned by the system view.

So how do I get both the value from the ToxicityName[n] column and the column name into my final data query?
